Blood Under the Door: How a Neighbor’s 911 Call Exposed a Bronx Boyfriend’s Deadly Knife Rampage.
Officers from the 44th Precinct responded swiftly to a harrowing 911 call early on the morning of February 28, 2026, after a neighbor reported blood seeping from beneath the door of an apartment at 956 Sherman Avenue in the Highbridge section of the Bronx. The call came in around 6:40 a.m., prompting police to rush to the third-floor unit where they discovered a scene of extreme violence: widespread blood splatter on walls, pools on the floor leading toward the bedroom, and clear signs of a brutal struggle.
Juan Rivas, 45, the live-in boyfriend of victim Yesenia Hall, 42, had allegedly carried out the attack moments earlier. According to police and court documents, Rivas armed himself with a knife and repeatedly stabbed Hall in the neck, torso, chest, back, and stomach, inflicting fatal wounds. When Hall’s 16-year-old son heard his mother’s screams from another room, he rushed in to protect her. Rivas then turned the weapon on the teenager, stabbing him in the neck, shoulder, cheek, and back. Despite his severe injuries, the boy survived the assault.
A 17-year-old neighbor, Shantrice Diamond, provided a firsthand account of the terror that unfolded. She was awakened by a loud thud and then heard Rivas yelling threats like “I’m gonna stab you.” Hall’s voice followed, screaming in agony: “Stop! Stop!” She continued pleading, “I am gonna die, I am gonna die,” before the sounds abruptly ceased. Diamond told reporters, “And like two minutes later I heard nothing but silence.” The sudden shift from desperate cries to complete quiet left an indelible mark on those who overheard the tragedy.
After the stabbings, Rivas reportedly changed out of his bloodied clothes—some accounts describe him fleeing in a construction worker’s outfit, including a neon vest and hardhat—and escaped the building around 6:40 a.m. Police recovered a bloody knife from the apartment, which became central evidence in the case. Blood trails extended down the stairwell and smeared hallways, indicating the ferocity of the incident.
The quick 911 response from the observant neighbor who spotted the blood under the door proved crucial. Officers from the 44th Precinct arrived promptly, secured the scene, and ensured both victims received immediate medical attention. Hall was pronounced dead at a local hospital, while her son was transported to Lincoln Hospital, where he stabilized and is expected to recover physically, though the emotional impact remains profound.
Rivas evaded capture for several hours, but a wanted flyer distributed by police led to his identification and arrest around 2:30 p.m. that same day. He was taken into custody without resistance and processed accordingly. On Sunday, March 1, 2026, Rivas was arraigned in Bronx Criminal Court on charges including murder, attempted murder, manslaughter, assault, and criminal possession of a weapon. Judge Yadhira Gonzalez-Taylor ordered him held without bail at Rikers Island, with his next appearance scheduled for later in the week.
The relationship between Rivas and Hall was described as domestic, with the pair sharing the apartment. No prior reported incidents of violence between them have been publicly detailed, but the attack fits patterns often seen in intimate partner violence cases, where tensions can escalate rapidly without warning signs visible to outsiders. Prosecutors highlighted the domestic context during the arraignment, emphasizing the severity of the wounds and the son’s heroic attempt to intervene.
Family members have spoken out about the boy’s courage, noting that he “was trying to save his mom” by confronting the attacker and attempting to de-escalate the situation. Relatives expressed heartbreak over Hall’s loss, describing her as a dedicated mother who worked tirelessly for her children. An adult daughter living nearby had called 911 upon hearing the disturbance but arrived to a devastating scene.
The Highbridge community reacted with shock and grief. Residents placed candles and flowers near the building entrance, and neighbors shared stories of the normalcy that had existed before the tragedy. The incident has reignited discussions about domestic violence awareness, the importance of community vigilance—such as the neighbor who spotted the blood and called for help—and resources for those in potentially abusive relationships.
Investigators continue to piece together the timeline and any possible motive, though none has been officially released. The physical evidence, including the recovered knife and forensic analysis of the blood patterns, is expected to play a key role in the prosecution’s case. For the surviving son, recovery will involve not only healing from stab wounds but also coping with the trauma of witnessing his mother’s murder and nearly losing his own life.
This case serves as a stark reminder of how quickly domestic conflicts can turn deadly and the vital role that alert neighbors and rapid police response can play in limiting further harm. As the legal process unfolds, the Bronx community mourns Yesenia Hall and rallies support for her son and extended family during this unimaginable time.
